Hi,
So you'll create new tables in SeedCodeData.fp7, and you'll add them to the graph and create layouts/tabs that use them in SeedCodeComplete.fp7
To create a new table, open Complete and select "Show Window" from FileMaker's Window menu and you'll see SeedCodeData as a widow. Select that window and then select "Manage / Database" from FileMake's File menu. Now you're in and can define fields and tables. You only need to create relationships in SeedCodeData to support things like lookups or calcs between tables: the normal relationships you'd set up for portals will be done in SeedCodeComplete.
So once your table is defined, you can return to SeedCodeComplete, add a table occurrence for the new tables to the relationship graph in Complete, and work with the table occurrence as if it were in Complete.
Some more notes about how the solution "separates" data and interface into these two files can be found here:

Yes, we usually copy one of the working scripts and modify it to create lines in the new table. The "new line" button on Event Details is a good one and the script it calls ("Create Invoice Line For Event") could be a model for your new inventory tally lines, but that script is probably more complicated than it needs to be inventory lines.
Since you're new to this you could just set the relationship up to "Allow the creation of related records" as that would create new inventory tally lines by simply typing in the next open row. Or if you needed a script but couldn't write it yourself, you could hire us to make the modification for you. Just
